"Sandy has been very generous with his time, advice, and intros from our early days and even to growth stages. He is a great thought partner, armed with market insights and thoughtful perspectives, and I'd recommend any founders to welcome his investment."

"Sandy was one of our first angels back in 2012, and looking back 10 years later, he's been our most helpful investor/advisor of all. He's been through the highs & lows of my entire entrepreneurial journey. He was the first person I called when I had to negotiate our Series A, B, C, and D term sheets - he's a world-class negotiator. He's also very sharp when it comes to product-led growth and botom-up SaaS. His connections are immense, and he always seems to know the best candidate for a pilot customer or just gathering market feedback. Sandy is absolutely the best!"

"At each step of our relationship, Mike and Sandy have served as critical strategists, advisors, and even business operations ringers as needed. From our initial M&A relationship, through to an investment that we took from them due, to the value that they proved time and again, they have added multiples of value beyond our expectations. We’d gladly partner with them again, which is why my co-founders and I are investing with them at horizon.vc"

“I can’t give a higher recommendation to HorizonVC. Sandy has been an incredible champion for me and my companies twice now - he’s helpful not only the softer ways like being willing to spend time with me to discuss thorny questions, but in a very roll-up-his-sleeves way by helping me identify potential customers, helping me close customers, constantly thinking of my company for hiring, and more. It’s rare to find an investor this helpful - I can honestly say he’s a meaningful part of the success with my last company, and will be a meaningful part of any success we have with my current one."

"HorizonVC will always be in your corner. Sandy has backed both of my software startups and has consistently gone above & beyond to be supportive and add value. I can count on him to provide thoughtful strategic advice, help brainstorm various GTM strategies, make helpful introductions, and to be ready to roll up his sleeves for us at any time."

"Sandy is not just an investor but a friend to the founders he backs. He is the first to reply to an investor update letter and jump on a call to listen to your concerns. When asked what qualities a founder should look for in an investor, I always say, find an investor that listens more and talks less. Sandy is that investor!"

"I highly recommend HorizonVC as a first check investor in any software startup. Sandy was one of our first investors at MineralSoft and was extremely helpful from the beginning all the way through to our exit. When I raised for my next startup, Sandy was on the top of my list to bring on as a first-check investor."
